HAMILTON, DECEASED SAFETY ATTACHMENT FOR YPOGRAP ICAL ooivrrosrive AND CASTING MACHINES Application filed March 12, 1927. Serial No. 174,768.

My invention relates to typographical machines of the general character and organization disclosed in U. S. Letters Patent No. 436,532, granted September 16, 1890, for

casting integrally, composed lines of type, and particularly machines adapted to employ double letter matrices, and to assemble matrices at either'one of two levels, to wit,

a lower and an auxiliary-level, and my in vention relates more particularly to a novel safety device adapted to be attached to the casting vise, and to the delivery channel re speotively, of the conventional forms of type casting machines of this character, and adapted to coact with the so called two letter attachment, filler piece or"flapper of such machines and the so called duplex rail thereof, in such a manner as automatically to lock the so called assembling elevator against any upward movement thereof, if both the two letter attachment or flapper and the duplex rail are in their auxiliary positions at the same time.

It is well known, that if, in the operation of machines of this character the matrices are assembled in the assembling elevator in the upper, or auxiliary position, by theuse of the so called duplex rail and the filler piece or two letter attachment, or the so called flapper is then positioned in operative alignment with the so called first elevator, by an oversight on the part of the operator, the matrices will be presented to the casting device of the machine, out of alignment with either one of the two matrix guides thereof.

The results of delivering, or attempting to deliver, matrices into the casting apparatus while misaligned, by the improper joint use of the duplex rail and the filler piece, may be various. Thus the misaligned matrices, upon being delivered into the casting apparatus may be broken or crushed so as to render them incapable of further use, or

parts of the casting apparatus are broken by l the excessive strain, or if the matrices are presented in a misaligned position with respect to the casting plate or die, and molten metal is delivered therethrough, such metal will flow past the matrices and squirt out 60 on either. side. This latter condition is what is usuall termed as a flapper squirt.

The 0 ject of my invention therefore is practically to eliminate any possibility of misalignment of matrices in the casting apparatus or while beingdelivered to the. casting apparatus, by providing novelmeans. cooperating. with the filler piece and the duplex rail, so as automatically to lock the assembling. elevator against any upward movement, in the event that the duplex rail and filler piece have both been improperly set into their operative or auxiliary positions.

With the above ends in view, my invention consists of a suitable locking bolt slidably mounted, preferably on the bottom of the delivery channel assembly, having a suitable projection, finger or catch member, adapted to interlock or interengage-with the.

near end of thevduplex rail of the assembling elevator, when said bolt or slide is in an outer, looking or operative position, and when the duplex rail of the assembling elevator is also in the inner or operative position. My invention further consists of certain actuating means intermediate the filler piece and said slide to displace the latter into said outer operative locking position.

For the purpose of illustrating my invention, I have shown in the accompanying In the accompanying drawings, illustrating my novel safety device for typographical composing and casting machines, and showing the parts of a conventional machine, to which the former is applied and with which the former coacts:

Figure 1 represents a front elevation of a fragmentary portion of a typographical composing and casting machine, or particularly a front elevation of the first elevator, casting vise, delivery channel and assembling elevator, to which the novel safety device, embodying my invention is attached.

Figure 2 represents a top plan view, partly in section taken on line 2-2 of Figure 1.

Figure 3 represents a top plan view of the safety device embodying my invention, shown detached from a conventional machine, and showing also the interlocking of the same, with the duplex rail.

Figure 4 represents a vertical section on line 44 of Figure 1, on a greatly enlarged scale, illustrating the outer or inoperative position of the duplex rail.

Figure 5 represents a section similar to that shown in Figure 4, illustrating the inner or inoperative position of the duplex rail.

Figure 6 is a fragmentary plan view of the duplex rail in the inner, operative or auxiliary position, and of the locking slide of my novel safety device, also shown in the outer or auxiliary operative position, and in locking engagement with said duplex rail.

Figure 7 represents a perspective view of my novel safety device, shown detached from a conventional typographical composing and casting machine, illustrating the relation thereof to the filler piece at one end, and the duplex rail at the other end.

Figure 8 represents a perspective view of a die or casting plate, of a conventional machine showing the two matrix guide channels thereof.

Figure 9 represents a side elevation in section of a casting die with a matrix abutting the face thereof in the lower aligned position as normally presented without the use of either duplex rail or filler piece.

Figure 10 represents a similar side ele vation to that shown in Figure 9, with a matrix abutting the face of the die in the upper or auxiliary position, as presented by the separate use of either the duplex rail or the filler piece.

Figure 11 represents a similar side elevation in section, of the die or casting member and showing the position of a matrix relative to said die member, as a result of v the improper combined or simultaneous use In carrying out my invention, I provide a slide 1. having a pair of elongated and preferably aligned spaced apertures 2 and 3, through which a pair of corresponding fastening screws 4 and 5 may be passed, which are then threadedly anchored in suitable threaded apertures in the lower portion 6 of the delivery channel assembly 7 of a conventional typographical composing and casting machine of the character stated. By this means, the slide 1 is mounted upon the lower horizontal surface of said delivery channel assembly 7, in a slidable manner, being capable of longitudinal displacement corresponding to the effective length of the apertures 2 and 3. One end of the slide 1 carries an upright locking member or catch 9, extending at a right angle to the slide 1, and preferably formed integrally therewith, by merely bending up a suitable portion of metal of which the slide is formed; said catch 9 having a suitable lower and substantially horizontal locking shoulder or ledge 10, disposed in operative alignment with the corresponding terminal portion 11 of the duplex rail 12, of the conventional form of machine, when said duplex rail is in the inner or auxiliary position.

The catch member 9 is so positioned with respect to the inner edge 13 of the duplex rail 12, that saidedge 13 will clear said catch 9, when the duplex rail is in the outer or normal position thereof and so that the terminal portion 11 of said duplex rail 12 will be brought into operative alignment with the catch 9 when said rail is in the inner auxiliary position.

Moreover, the extreme edge 14 of the catch 9 is so positioned with respect to the edge 15 of the terminal portion 11 of the duplex rail 12, that said edge 15 will clear the edge 14 of the catch9 when the slide is in the retracted or inoperative position shown in Figure 7, and so that said terminal portion 11 of the duplex rail 12 is in operative alignment with the catch 9 when the slide 1 is in the right hand or operative position thereof. 7

In order to retain the slide 1 and hence the catch 9 normally in the retracted position (shown in Figure 7 a suitable tension spring 16 may be interposed between the head 17 of the stationary screw a and a suitable anchor 18 fixedly secured to the slide 1.

The outer end of the slide 1 is provided with a downwardly extending vertical flange 19, disposed substantially at a right angle to the slide 1 and preferably formed integrally therewith and having a suitably inclined or curved lip portion 20.

In order to actuate the slide 1, that is, to displace the same in a direction towards the terminal portion 11 of the duplex rail 12, whenever the filler piece 21 is positioned in the auxiliary or operative position, I propiiece'21. The eccentric member 22 is provided with an annular peripheral groove, in

which is seated an annular eccentric strap- 2a, carried at one end of actuating rod 25; the opposed end of which is provided with a downwardly extending right angular pivot pin 26. y

A suitable bracket 27., having an upper horizontal portion 28, is secured to any suitable portion of the casting vise 29, by means of the screw 30. Upon the upper horizontal portion 28, a rocker arm 31 is pivotally secured, by means of the pivot screw 32, so as to permit of oscillation or deflection thereof about a vertical axis. The front end 33 of said rocker arm 31 is provided with a suitable aperture 34, which is adapted to receive the pivot pin 26 of the actuating rod 25, whereby a pivotal connection may be maintained between the rocker arm 21 and said rod 25. The rear portion 35 of the rocker arm 31in turn is provided with a curved or inclined terminal edge 36, in

juxtaposition to the curved lip portion 20 of the vertical flange 19 carried by the slide 1 and. is adapted to bear against the latter when the rocker arm 31 is deflected by the rotation of the eccentric member 22, as will be seen from Figure 7.

It will thus be seen, that if the filler piece 21, carried by the shaft or spindle 22, is positioned in the right hand or operative position, the rocker arm 31 will be deflected,

, with the rear portion 35 thereof displacing the slide 1, against the tension of the spring 16 in the direction of the duplex rail 12. If the matrices 37 are thus assembled in the lower or normal position shown in Figure though said catch has been displaced towards the duplex rail 12 in the direction of the arrow 38, by means of the eccentric 2'2 and the rocker arm 31. The matrices thus assembled will, due to the action of the filler piece 21, be presented to the casting vise- 39, in the upper or auxiliary position shown in Figure 10. If on the other hand, the filler piece 21 is also in the auxiliary or right hand position, and the duplex rail 12 is set into the inner or auxiliary position, so as to assemble the matrices 37 in the upper or auxiliary position shown in Figure 5, then the terminal portion 11 of the duplex rail 12, will be positioned directly beneath the hori- Zontal ledge or shoulder 10 of the catch 9, so as to be encountered thereby when the assembling elevator 1O is attempted to be raised. This interengagement of the catch 9 and the terminal portion 11 of the duplex rail 12, automatically locks the assembling elevatordO before it can reach its upper'or delivering position, thereby preventing the matrices 37 from being presented to the die 39 in the misaligned position shown inFige ure 11. r a
